hello,

i tried to calculate the flow through two combined cylinders...
meshing tool was netgen.
it is one of the example geometries of netgen...

but simpleFoam solver always breaks the operation after 23 steps of calculation.
it points out the following errors in the terminal windows:

#0 Foam::error:rintStack(Foam::Ostream&) in "/opt/openfoam170/lib/linux64GccDPOpt/libOpenFOAM.so"
#1 Foam::sigFpe::sigFpeHandler(int) in "/opt/openfoam170/lib/linux64GccDPOpt/libOpenFOAM.so"

#8 __libc_start_main in "/lib/libc.so.6"
#9

Floating point exception


could someone help me, how to get this case run?

i also postet the "0" time directory and system folder
constant folder was a bit to large

thank you very much in advance
